    Article Snippet: The silent information regulator T1 (SIRT1) is linked to longevity and is a crucial mediator of osteoblast function.. We investigated the direct role of Sirt1 during bone modeling and remodeling stages in vivo using Tamoxifen-inducible osteoblastspecific Sirt1 conditional knockout (cKO) mice. cKO mice exhibited lower trabecular and cortical bone mass in the distal femur.. These phenotypes were coupled with lower bone formation and bone resorption.
